ELECTRIC FIXTURE.

Specification of Letters Patent.

Patented Oct. 11, 1921.

Application filed November 11, 1920. Serial No. 428,400.

To all whom it may concern Be it known that I, FRANK L. BUTLER, acitizen of the United States, and a resident of Chicago, in the countyof Cook and State of Illinois, have invented a newand useful Improvementin Electric Fixtures, of which the following is a full, clear, and exactdescription.

My invention relates to improvements in electric fixtures, and itconsists in the combinations, constructions, and arrangements hereindescribed and claimed.

an object of my invention is to provide an improvement over the deviceshown in my prior application for Letters Patent on an electric fixtureSerial No. 414,212, filed October 2, 1920, in which I disclosed afixture having a hollow stem incased for a portion of its length, formedwith a lateral aperture through its wall, and provided with a plug forguiding the electrical conducting wires from the stem through thelateral aperture, said improvement consisting in the provision of a stemhaving more efficient and practical means for guiding the electricalconducting wires from the stem through the aperture in the wall thereofand being adapted for direct connection with an element in a lightingfixture, such as a mounting for a globe, shade, or the like.

A further object of my invention is to provide a device of the typedescribed having a novel means for guiding the electrical conductingwires from the stem through an opening in the wall thereof, such meansbeing removable and possessing inherent qualities operating to maintainthe same in adjusted position.

A further object of my invention is to provide a device of the typedescribed'in which the number of elements is reduced to a minimum,wherefore the device can be produced commercially at a comparatively lowcost.

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particularly pointed outin the appended claims.

My invention is illustrated in the accompanying drawings, forming partof this application, in which Figure 1 is a central section through thedevice,

Fig. 2 is a similar view of a fragmentary In the form of the deviceshown in Fig. 1, the

stem 4: is formed of any suitable insulating material, such as anindurated fiber. A casing 6 is mounted on the stem 1, encircling thelower portion thereof and is provided with an inwardly extending flange7 at its lower end curved to conform with the contour of the end wall ofthe stem 4% and arranged to lie snugly thereagainst to protect the same.The bore of the stem 4 is threaded interiorly at 8 for engagement with aclose nipple 9 that projects beyond the end thereof. An elbow 10 fittingon the projecting end of the nipple 9 maintains the casing 6 in positionon the stem 4 and is adapted for direct connection with the mounting ofa lighting fixture, (not shown) such as the socket for a shade, globe,or the like.

The stem 4 has an obliquely extending opening 11 through its wall at aspaced distance from the upper end thereof. Electrical conducting wires12 are passed into the bore of the stem l through its lower end and mustthen be projected through the side opening 11 and extended forconnection with the conducting means (not shown) that are in the wall 3.Considerable dii'liculty in fishing the wires 12 from the bore of thestem has been experienced prior to my invention. To provide means forguiding the wires 12 through the opening 11 when portions thereofprojecting beyond the end of the stem & are moved toward the same, isone of the objects of this invention. To this end a groove 13 adapted toreceive the laterally bent end 1 1 of a guiding spring clip 15 isprovided in the inner wall of the stem 4. The guiding clip 15 is formedas best seen in Fig. 4 of the drawings and c0mprises diverging arms 16and 17. The arm 16 is arranged to extend along the inner wall of thecasing l diametrically opposlts the opening 11 and terminates in thelaterally turned end 141- that is received within the groove 18. Thecurved arm 17 is folded backwardly at 18 and the end portion thereof isthen bent at 19 to extend along the inner wall of the casing 4', therebyprovid ing a socket 20 adapted to engage with the angular edge portion21 of the upper wall of the opening 11. Theguiding clip 15 is preferablyformed of material having spring qualities operating to maintain theclip in the position illustrated, since the arm 17 is forced slightlytoward the arm 16 when the clip is placed Within the bore of the casing4. A canopy 22 is mounted on the casing 6 and secured in adjustedposition therealong by means of a set screw 23.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. The electric conductingwires 12 may be instantly passed through the stem 4: and therefromthrough the lateral opening 11 without any appreciable effort, since theguiding clip 15 will guide the inserted ends of the wires from theopening 11 without hindering the progress of the same. The clip 15 maybe quickly placed in operative position when the fixture is beinginstalled.

Referring now to Figs. 2 and 3, I show modified forms of the samedevice. Like parts in the several figures have been designated'by thesame reference characters and I shall accordingly confine my descriptionof the modified form of the device to parts thereof that differ from theparts in the preferred form of the device. Referring now particularly toFig. 2, I show the stem 4 and the casing 6 horizontally disposed as whenthe device is applied to a fixed support projecting from a side wall. Abracket 25 has an interiorly threaded portion 26 engaging with theprojecting end of the nipple 9 and held in adjusted position therealongby means of a set screw 27. The electrical conducting wires 12 pass intothe stem 4 from a lamp socket, or the like (not shown) that is mountedin and supported by the bracket 25. Referring now to Fig. 3 of thedrawings, I show a metallic stem 30 threaded at its upper end at 31 forconnection with the coupling 1 or with an insulating joint (not shown)if the requirements of the service for which intended are such that thefixture must be insulated. The stem 30 is formed with anobliquelyextending lateral opening 32 similar to the opening 11 and is incasedfor a portion of its length by a casing 33. It will be under.- stoodthat the finish of the casing 38 will correspond with that of the canopy22 and that the stem 30 will be entirely concealed from View when thedevice is assembled and installed. The guiding clip 34 has an arm 35extended to the upper end of the stem 30 and then bent outwardly at 36to overlie the end wall thereof. A curved diverging arm 37 extendsobliquely across the bore of the stem 30 and is folded backwardly at 38and then upwardly at 39 to engage with the inner wall of the casing 30and to provide a socket 4:0 adapted to receive the angular edge portion41 of the wall of the opening 82. The guiding clip 34 has springqualities and performs the same function in the modified form of thedevice as the guiding clip 15 in the preferred form of the device. Theelectrical conducting wires 12 are passed through the opening 32.

I claim:
